12 volt voltage gauge 8M0052864 works with all SmartCraft compatible engines. Round, white gauge face. Fits in 2-1/8 in. (52mm) hole. Application of this gauge will depend on the individual engine model and its sensors. Bezels are sold separately from each instrument allowing for the boater to select the color of their choice to compliment or contrast with the face of the instrument. SC100 System Link gauges allow you to monitor vital engine and boat functions with digital accuracy. Furnished with a fog resistant lens, these gauges can be "daisy chain" interfaced between other SmartCraft products using a plug‑in connection. SC100 link gauges can be connected to a SC1000 System Tach, a MercMonitor or System Monitor.
